Abstract
Perovskite layer is formed by sandwich evaporation technique (SET) process. First, spin coating CH3NH3I (MAI) and thermal evaporate PbI2. Second, evaporate MAI at low pressure by SET chamber. Through the double-interdiffusion of MAI and PbI2, we adjust the reaction conditions by different evaporation time and chlorobenzene added, which called anti-solvent vapor-assisted crystallization (AVC), can spend less time and cost to make better morphology of perovskite crystallize and enhance to high PCE=13.08%. ? 2021 IEEE.
